Billionaire Nick Hanauer, who's become well known for speaking out about the dangers of rising inequality, tells his fellow "zillionaires": I’m not the smartest guy you’ve ever met, or the hardest-working. I was a mediocre student. I’m not technical at all—I can’t write a word of code. What sets me apart, I think, is a tolerance for risk and an intuition about what will happen in the future. Seeing where things are headed is the essence of entrepreneurship. And what do I see in our future now? I see pitchforks. At the same time that people like you and me are thriving beyond the dreams of any plutocrats in history, the rest of the country—the 99.99 percent—is lagging far behind. But the problem isn’t that we have inequality. Some inequality is intrinsic to any high-functioning capitalist economy. The problem is that inequality is at historically high levels and getting worse every day. Our country is rapidly becoming less a capitalist society and more a feudal society. Unless our policies change dramatically, the middle class will disappear, and we will be back to late 18th-century France. Before the revolution. And so I have a message for my fellow filthy rich, for all of us who live in our gated bubble worlds: Wake up, people. It won’t last.
